While the button layout presets are nice for the casual players, it is flawed when it comes to those who don't fit into one of the options.
And yes, the PS4 has a work-around via button assignments, but that's also a console-wide change and makes menu operation a chore. Please just give us some way of altering the existing options to fit our preferred control schemes.
If not that, give us more options to choose from. I just want a way to have jumper but be able to crouch with R3 and melee with R2 (using swapped shoulder buttons), leaving grenade on circle.
